Santa Monica Channel Rubber Dam


The County of Los Angeles Flood Control District maintains an existing low-flow diversion berm within the flood channel. The $2 Million project removes the existing berm and replaces it with a 4-foot high by 37-foot wide air inflatable rubber dam, approximately 400-feet upstream of Pacific Coast Highway. The dam is diverting winter dry-weather flows from the storm drain system to the City’s sanitary sewer system in order to help the City meet requirements mandated by the Regional Water Quality Control Board and the US EPA for the Santa Monica Bay Beaches.
